Alex McKnight is happier than he can remember being in a long time. And it's all because of a woman - Natalie Reynaud, a Canadian police officer. When they take a romantic weekend together at an old luxury hotel, however, they receive an unexpected message - someone has left a hat filled with snow, and a note that reads, "I know who you are." As Alex searches for an explanation, he must face up against a terrible Reynaud family secret, a secret that to this day still drives men to kill.
